Question

Beavers build dams that create wetlands, providing new habitat for fish, birds, amphibians, and insects that wouldn't otherwise live in the area. What ecological role do beavers play?
Question 8 options:

Specialists that only affect other beaver populations directly

Competitors that reduce resources available for other wetland species

Ecosystem engineers that create and modify habitats for other species

Parasites that harm existing wetland ecosystem communities

Answer 1

Ecosystem engineers that create and modify habitats for other species.

Beavers physically alter their environment (building dams) in ways that create new wetland habitat and influence community structure.
